Ubunzima bungenye yezalathisi ezisetyenziswa ngokuqhelekileyo kwiipropati zemishini yezinto zetsimbi.Uvavanyo olukhawulezayo nolunoqoqosho lwendlela yovavanyo lokuqina luyaziswa kumzi mveliso wocingo.Kodwa ngenxa yokuqina kwezixhobo zetsimbi, akukho ngcaciso imanyeneyo necacileyo kubandakanya zonke iindlela zovavanyo ekhaya nakwamanye amazwe.Ngokuqhelekileyo, ukuqina kwentsimbi kudla ngokucingelwa njengokuchasana kwempahla kwi-deformation yeplastiki, imikrwelo, ukunxiba, okanye ukusika.
Kuhlengahlengiso lomgama wokudipha omkhuluucingo lwezinki, gcina isantya sokuqala singatshintshi, kwaye unqume ixesha lokuntywila (1) ngokutsho T = KD, apho: T yinto ehlala ixesha lokuntywila, thatha i-4-7d yi-diameter yocingo lwentsimbi mm, uze uqikelele ukudipha. umgama.Ngokuhlengahlengisa umgama wokudipha i-zinc, ixesha lokudipha i-zinc yocingo lwetsimbi lweenkcukacha ezahlukeneyo lifinyezwa ngama-5 ngokomyinge kunalo ngaphambi kohlengahlengiso.Ngale ndlela, ukusetyenziswa kwe-zinc kuncitshisiwe, kwaye ukusetyenziswa kwe-zinc ngetoni yocingo lwensimbi kuncitshiswa ukusuka kwi-61kg ukuya kwi-59.4kg.
Idiphu eshushu yediphu isetyenziselwa ukufudumeza i-zinc dip plating etyhidiweyo, isantya semveliso, ukutyabeka okutyebileyo kodwa okungalinganiyo, ubukhulu bemarike buvumela i-microns ezingama-45, ukuya kuthi ga kwi-300 microns okanye ngaphezulu.Umbala umnyama, ukusetyenziswa kwentsimbi ye-zinc, kunye nentsimbi ye-matrix ukwenza umaleko wokungeniswa, ukuchasana nokugqwala kulungile, indawo eshushu ye-galvanized yangaphandle inokugcinwa amashumi eminyaka.Kukho imigaqo emibini yokukhusela i-zinc coating kwi-matrix yensimbi: kwelinye icala, nangona i-zinc isebenza ngakumbi kwaye kulula ukuyikhupha kune-iron, ifilimu yayo ye-oxide ayikhululekile njenge-iron oxide kwaye iyancipha.Ukubunjwa kwe-dense oxide layer phezu komhlaba kuthintela i-oxidation eyongezelelweyo ye-zinc ngaphakathi.
Ngokukodwa emva kokupasa kwe-galvanized layer, i-face oxide layer ixinene ngakumbi, ngokwayo inokumelana okuphezulu kwe-oxidation.Kwelinye icala, xa umaleko womphezulu we-zinc coating wonakalisiwe, uveza i-matrix yentsimbi yangaphakathi, kuba i-zinc isebenza ngakumbi kune-iron, i-zinc iya kuthwala indima yombingelelo we-zinc anode, i-zinc iya ku-oxidize phambi kwentsimbi, ngaloo ndlela ikhusela umaleko wentsimbi. kumonakalo.
